Hi.
I am setting a hymn, using the satb.ly template, that has an A1A2B
structure where there are different lyrics for A1 and A2 and the same
music. My first attempt is:
\version "2.24"
SopranoMusic = \relative {
\repeat volta 2 {a' a a a }
}
AltoMusic = \relative { f' f f f }
TenorMu
I am trying to look into if a particular layout is possible with
Lilypond. I'd like to display small groups of short musical examples as
a "table", or "staggered". I'm not sure what to call it so I've attached
a photoshopped markup of what I am trying to achieve.
I'd like to display it this wa

Sure, that is also something where it would be nice to actually have a list of

Good point, I didn’t think of that! Also I know that using a callback on
bound-details would work as well, but I’m not sure if this is the best way to
replace a single value in an alist (what if you want to change other parts of
the alist independently?).
Maybe the whole transformer thing shoul

If you add another red text spanner, you will see that it gets the text "foo"
in spite of \once.

You just forgot to wrap the expression in `(lambda (grob) ...)` .

Hello Trevor,
instead of trying to use a callback on bound-details.left.text you can use the
before-line-breaking and after-line-breaking hooks to modifiy this property:
%%% BEGIN %%%
\version "2.24"
% no left text set
{
\once \override TextSpanner.before-line-breaking =
#(lambda (grob)
Hi,
Two examples appear below.
The first works; it uses \override with a callback.
The second doesn't work; it attempts to use \tweak with a callback:
%%% BEGIN %%%
\version "2.25.3"
\markup "Conditionally colors both tuplet brackets:" \markup \vspace #1
{
\once \override TupletBracket.colo
